Fact three: An Aquarium Maintenance Business may have you reeling in the big ones.
What the Business Involves:
As you might guess, you'd clean aquariums in your client's homes or offices. Basically, you empty the water (AFTER you've moved the fish to a safe bowl or pan), scrub and clean the tank, replace the water and finally return the fishies to their nice clean tank.
Knowledge or Skills Required:
Fish are delicate creatures; you have to know what you're doing, what chemicals to use and which chemicals you should avoid (for example, it may be tempting to cut that fishy smell with an ammonia-based cleaner, but don't do it - ammonia kills fish.)
Other than that, you'll need an assortment of cleaning equipment, such as rubber gloves, buckets, bleach, a siphon for the water, gravel vacuum and towels. And a dependable car to get you to and from your client's home or office.
Not many people like to clean fish tanks; consequently, not many people specialize in this business!
You can add to your profits by selling aquarium power filters or fish food and decorations
